Specification of Letters Patent.

' PAPER-HEATER FOR PRINTING-PBESSES.

Patented llllar. 9., 1915.

Application filed April 23, 1914. Serial No. 834,016.

To all whom it may concern:

. Be it known that I, MICHAEL-CLINTON, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented quickly dried; the quality of the printing.

is improved, and various other advantages that will appear from the specification are secured.

Figure 1 is a front view of a portion of a press showing my invented device and .the parts most nearly connected with it. Fig. 2 is a side elevation of the parts shown in Fig. 1'. Fig. 3 is a section on line mm of Fig. 1. Fig. 4 is a section, on the line m-m of Fig. 2, of a slightly modified form ofthe heated cylinder. Figs. 5 and 6 are top and bottom views of the bridge cam. Fig. 7 is a side elevation of the revoluble steam coupling; Fig. 8 is a front elevation of a heating cylinder and cylinder of the press; Fig. 9. is a side elevation of the parts shown in Fig. 8. Fig. 10 is a view of the stop used in the devices for giving a yielding motion toward the cylinder; Fig. 11 is a detail showing the roller bearing mounting of the paper heating tube; Fig. 12 a detail of the mounting of the tube from the frame of the press,

steam pipe is connected to a source of steam supply (not shown) which can be either exhaust or live steam. The cylinder 3 is mounted upon the pipe 9 by roller bearings held in case 1, which are placed at the ends nearly fills the cylinder 3.

of the cylinder 3 (see Fig. 11) and enable the cylinder to revolve veryfreely so that sllght frictional contact between it and the surface of the cylinder or the paper, will revolve it. The even heating of cylinder 3 throughout its length is promoted by keeping the space between the interior of its walls and the steam heated metal small. This can be done by placing'an extra tubing 4 over the pipe 9, (see Fig. 3) or by connecting the pipe 9 to a larger pipe 2, which (See Fig. .4.) The cylinder 3 is held, during a part or the whole of the cylinder 5 revolution in yielding contact with it. Cases arise, however, when it is desired to give the cylinder ards 8 from a shaft 14: of the press. Each V of these standards is provided with set screws 7, 7. The springs 13, 13 hold the cylinder 3 yieldingly against the cylinder 5. These springs 13, 13, are attached to the ears 16, 16, on the frame 33 and to the pipes 11. The elbows 10, 10 connect the pipes 9, 9, to the pipes 11, 11. If the give of the pipes is not sufficient to allow cylinder 3 to be brought into contact with the cylinder 5 by the springs 13, 13, I use a revolving coupling (see Fig. 7) in which the coupling 15 is rigidly connected to the pipe 11, while the pipe 17 is rotatably connected and is 1 open, or where there is something on the surface of the press cylinder which the cylinder 3 must be pushed back to allow to pass. cam, 50, 50, bridges the open space in the cylinder 5 and carries the cylinder 3 over the open space. The cams, 50, 50, can be raised sufficiently to push back the cylinder 3 so that it will clear the fingers 53. -A convenient form of this cam construction is shown in Figs. 4, 5 and 6, where the cam is provided with rider 56, having sloping ends 57, 57. The lugs '51 and 54: fit back of the walls of the cylinder 5, and are provided with the set screws, 53 and 58. Screw 53 passes through the rider 56, and the wall of cylinder 5, and screw 58 passes through lug 54 and clamps against the interior of-wall illustrate a form where the flanged wheels 6%, 6% are mounted on the pipe and ruin ning on the end hoops 71, 71, of the cylinder 5, are used to preserve the distance between 5 cylinders 3 and 69 is a ball bearing placed between pipe 9 and wheel 64. here a lift is to be given, to cylinder 3, for instance, to pass over the fingers 30 or the sockets 65 and 66, a rider cam 68 is placed on the cylinder end hoop 71 where this push is desired to be given.

Where it is desired that the movement of the cylinder 3 toward the cylinder 5 be limited, a slot is cut extending part way around the shaft 14, so that by pro ecting set screw 7 into it the revolution of link 8 upon'it is limited. This slot can have two steps 61, 62, so that by projecting the screw 7 to varying depths in the socket 63, the amount of the rotation permitted to link 8 can be varied. The set screws 7 may also be set tight and the link 8 held in rigid position.

I claim 1. The combination with the cylinder of a printing press of a revolving heated cylinder yieldingly impelled toward the cylinder of the press.

. 2. The combination with the cylinder of a printing press, of a heated cylinder, yieldingly impelled toward the cylinder of the press, and stops limiting the movement of the heated cylinder toward the cylinder of the press.

3. The combination in a paper heater for printing presses, of a heating pipe, and a freely revoluble cylinder surroundingv the heater pipe and turning on roller bearings thereon, the exterior walls of the heating pipe between these bearings lying close to but not touching the interior of the cylinder,

and being of substantially larger size than the portions of the heater pipe carrying the bearings.

4. The combination, in a paper heater for printing presses, with the cylinder of a printing press of a heating cylinder yieldingly impelled toward the cylinder of the printing press and a distance maintainer, operatively connected between the heated cylinder and the cylinder of the press.

5. The combination, in a paper heater for printing presses, with "the cylinder of a printing press, of a heated, freely revoluble cylinder, yieldingly impelled toward the cylinder of the printing press, of wheels mov- .3 ing toward and from the press cylinder with the heated cylinder but revoluble independently of the latter, and running upon the press cylinder.

6. The combination, in a paper heater for printing presses of a freely revoluble heated cylinder, with the press cylinder, a space maintainer operatively connected between the press cylinder and the heated cylinder and a spacing cam upon the press cylinder.

7. In a paper heater for printing presses, the combination with the cylinder of a printing press, of a shaft having a slot therein extending part way around the shaft, a link revoluble about this shaft, a set screw set in said link and projecting into the slot in this shaft, a heating pipe and a revoluble heated cylinder carried by the heating pipe.

In testimony whereof I aliix my signature in presence of two witnesses.

MICHAEL CLINTON.
